Plot Summary
Dr. Cara Harding (Julianne Moore) is a dedicated psychiatrist skeptical about the nature of certain afflictions, especially Multiple Personality Disorder. Her skepticism starts to give way when her father, Dr. Harding (Jeffrey DeMunn), introduces her to a patient named Adam (Jonathan Rhys-Meyers) who consistently assumes the personalities of murder victims. Cara's work with Adam puts her and her daughter Sammy (Brooklynn Proulx) at risk of becoming victims themselves.
